Introducing Eidolon One
A dry-EEG headband that notices the moment you fall asleep and plays a short audio cue built around a topic you chose. Four steps, every night.
Step 01
Onset detection
Finds the window while you drift
Dry-EEG sensors read the moment you slip from waking into early sleep — the narrow window where the mind is most open — without anything to set up or press.
